WRENCH.

To @ZZ fr/wm it may @0f/toorn i Be it known that 1, ORSON MONROE Rosie,

` a citizen of the United States residing -at Medford, in the county ofJackson and State of Oregon, have invented knew and useful Improvementsin `liVreiiclies, of which the following is a specification.

The present invention relates to improve-` ments in wrenches, andresides in the construction, combination and arrangement of parts setforth in the following specification and falling within the scope of theappended claim.

1n the drawing: Figure 1 is a" perspective view of a wrench constructedin accordance with the present invention, Fig. 2 is a centrallongitudinal sectional view through the saine, and Fig. 3 is aperspective View of the movable jaw detached looking toward ,theunderface thereof.

Referring .now to the drawings in detail, the numeral 1 designates amonkey wrench constructed in accordance with the` present invention.`This wrench includes a stationary jaw 2 which is formed upon the outer'end of a substantially rectangular body portion 3, the said body being,of course, disposed at a right angle to the jaw proper. The bodyterminates in a rightv angular shoulder 4, the said shouldercommunicating with the longitudinally extending shank 5 of the wrench.The body has its lower face, at its juncture with the shank 5 `and withthe outer face of the jaw 2, preferably inclined, as shown in thedrawing, and two of the opposite walls or the faces of the shank areprovided with-threads 6, the said threads being rounded to co-act with`similar threads formed upon. the boie of an operating sleeve 7. Thesleeve 7 has its inner end, or its end adjacent the j aw 2 and shoulderprovided with an annular flange 8, the same having a smooth outersurface, while tlie` outer surface of the operating sleeve'is preferablymilled, as shown in the drawing. The flange 8 is adapted to be receivedwithin a transverse recess or throat9 formed upon the rear portion of acarriage 10. This carriage is adapted to `be disposed over the shank 5and opposite the shoulder 4 of the body 3 of the wrench, and is alsoadapted tov contact with the said shoulder 4 to limit the movement ofthe body in, what may `be termed, an inward direction, the outwardmovement of the body and sleevebeing restricted through the medium of ahandleV y `Specication of Letters Patent.

pression 12, and the carriage atfthe rear an upstanding` member 13,which provides y purpose which will presently be described.

The movable Jaw,

body 15; The body 15 has its outer en 1G, .the lowerl'end of the saidtail being rounded in cross section and is adapted to be receivedwithinthe rounded groove or recess 12 of the carriage'lO. The tail, above itsrounded portion, is adapted to contact with the wall of the portion 13of the carriage, and so to limit the outward swinging of the movable jawwith relation to the carriage.

.f lhe body 15 of the movable jaw 14 hasits inner facecentrally providedwith `a longitudinally extending depression or channel lwithin which issecured` one end of a `fiat spring' 18, the said spring bearing upon thestraight face of the body 3 of the stationary jaw 2, and as aconsequence swinging the movable jaw 14 outwardly therefrom, so as toprovide a substantially flaring mouth or en-` trance between the aws 2and 14:. The cai'- riage 10, it will be noted, comprises only asubstantially rectangular block, and is arranged only upon the face oftheshank adjacent the said shoulder 1 of the body 3, and

in order to sustain the said carriage upon the shank and to retain thetail able awvwithin the opening provided therefor in the carriage l0, Iemploy a substantially U-shaped yoke 19, the under wall of which beingrounded to correspond with the rounded threads 5 upon the lower face oftheshank, the side walls being straight and beingsecured to the carriage10 through the medium of removable elements in the nature of pins 20. jb

From the above description, taken in connection with the accompanyingdrawing, the simplicity of the device, as well as the adfurther detaileddescription. y

Having thus described the invention, what I claim is:

A wrench including `a body having a sta-` 11'which is secured upon the`shajnk. The carriage 10 is provided upon its upper'face with atransversely arranged roundedde-` b b indicated by the numeral 14,includes a jaw proper and an angu'larly `arranged longitudinallyextending1 of the movvantages thereof will, it is thought, be perfectlyapparent to those skilled in the art i to which such inventionappertains without iio 60 wall of the said depression is formed withtionary jaw, said body having one of its ends formed with a straightWall providing i a shoulder, the body below the shoulder being providedWith a longitudinally extending shank having two of the opposite Wallsthereof threaded, an operating sleeve having a threaded bore arrangedupon the shank and cooperating with the threads thereof,

` said sleeve having an annular iange for one of its ends, a carriagearranged over the shank opposite the shouldered Wall of the body, saidcarriage having a throat receiving the flange of the operating sleeve,the carriage having a transverse annular open- ',ing and being providedat the rear Wall of v the opening with an upstanding member dovvnturnedtail, the lower portion of which being rounded and adapted to bereceived Within the rounded opening in the carriage and the said tail,above its rounded portion, adapted to Contact With the upstanding wallof the Carriage, the body of the movable jaw having a longitudinalchannel, a fiat spring having one of its ends secured Within thechannel, the opposite end of the spring bearing upon the body of thestationary jaw, a yoke surrounding one of the threaded faces and two ofthe sides oi the shank and adapted to have its side Walls Contact Withthe tail of the movable jaw, and means 'for removably seouring the yoketo the carriage.
